CARD-INDEX.

Specification of Letters Patent.

Patented Feb. 1W, IWLW.

To all whom it may concern:

Be it known that I, JAMES II. RAND, a citizen of the United. States, residing at North Tonawanda, in the .county of Niagara and State of New York, have invented new and useful Improvements in Card-Indexes, of which the following is a specification.

This invention relates to the guides of card indexes and filing devices.

In some lines of business, such for example as life insurance companies, a very large number of record units and guides are required. The same is true of public and other libraries. In such cases, compactness is of the utmost importance as regards the guides as well as the record cards. Guides constructed of metal or heavy paper are objectionable because of their thlckuess, while those having eyelets or other projections are equally unsatisfactory on account of taking up too much room.

One of the objects of my invention is'the provision of a guide which is exceedingly thin and compact and yet possesses the required stifi'ness and durability.

A further object is to so construct the guides that one can readily see whether any papers have been left in the ockets or spaces between the guides, this being imporxr i; tant in the check and note files used in banks.

In the accompanying drawings: Figure 1 1s a perspectlve new of a. card index provided with the improved guides.

Fig. 2 is a perspectiveviewpf one of the guides. Fig. 3 is a similar vlew of a modied construction of the guide.

Similar characters of reference indicate.

corresponding parts throughout the several views.

1 indicates the body of the guide provided iv with. a suitable tab for an index slip or label. This tab may be in the form of a pocket 2 in which the slip 3 is inserted, the slip being either removable or permanently secured in the pocket, as preferred. The tab may be inclined or perpendicular to the body of the guide, as desired.

The guide and the tab or pocket are formed of a single blank of suitable transparent material, a comparatively thin sheet out unduly increasing its size.

'These improved guides are desirable not only for card indexes, but also for indexed files of various kinds, such for instance as bank check and note files. By constructing the guides of transparent material, the papers behind them are clearly visible, en-

abling the user to see whether any papers have been left between two guides by mistake and avoiding oversights. This feature is especially important in check files.

As the tab or pocket is integral with the guide, the body/thereof is free from the usual eyelets or other projecting fastenings which increase the bulk and thickness of the" guide. This one-piece cqnstructure, more over, materially reduces the cost of the guide.

In some cases, the body of the ide may contain two thicknesses of maternal, if desired, as shown in Fig.- 3. In this modification, a single sheet of celluloid is doubled crosswise in the middle and its fold is expanded to form a pocket 4: for an index slip 5, the two plies being secured together preferably by a transparent cement.

I c aim as my invention:

L'An index-guide provided at its top i with a pocket for-an index-slip, the body of the gulde and said pocket being formed from a single sheet of celluloid. v
